description/ordering information

The MAX3222 consists of two line drivers, two line receivers, and a dual charge-pump circuit with

±15-kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the

requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication

controller and the serial-port connector. The charge pump and four small external capacitors allow operation

from a single 3-V to 5.5-V supply. The device operates at data signaling rates up to 250 kbit/s and a maximum

of 30-V/

µs driver output slew rate.
